Embodiment Construction

[0017] An upward-sloping trapezoidal wave interface device for a three-swirl biomass gasification burner, which is mainly composed of an annular trapezoidal wave interface and a narrowing-shaped reducing chamber, and the narrowing-shaped reducing chamber is inserted obliquely from the right side into the furnace body Among them, the annular trapezoidal wave interface is connected and fixed at the center position above the grate, and the annular trapezoidal wave interface is fixed at the bottom of the shrinking reduction chamber, wherein, the bottom of the annular trapezoidal wave interface is uniformly distributed with a narrow lower part and a wider outer part. Wide and narrow trapezoidal openings, the trapezoidal openings are evenly distributed at the bottom of the annular trapezoidal wave interface. The application method of the upward inclined trapezoidal wave interface device for a three-swirl biomass gasification burner is: during use, the furnace body The grate at the bo...

Abstract

The invention relates to an upward-inclined trapezoidal wave interface device applied to a three-cyclone biomass gasification combustor and belongs to the technical field of biomass combustion equipment. When the three-cyclone biomass gasification combustor is in a use process, fuel is combusted to form gas; the gas flows smoothly via annular trapezoidal openings which are uniformly formed in thebottom of an annular trapezoidal wave interface; the flow speed of the gas is reduced; the quantity of sparks carried in the flame in combustion of the three-cyclone biomass gasification combustor canbe effectively reduced; meanwhile, under the effect of a necking type reduction chamber, the speed of the gas is effectively reduced and the gas is gathered at the top of an annular square opening; under a heat accumulation effect, hot gas flow can obtain a relatively high reduction temperature, thus the carbon dioxide in hot smoke which enters the reduction chamber from an annular fire layer anda bottom fire layer can be effectively reduced into carbon monoxide; the fuel is effectively combusted; and smoke emission is reduced.

Description

technical field [0001] The invention relates to an upwardly inclined trapezoidal wave interface device for a three-swirl biomass gasification burner, belonging to the technical field of biomass burning equipment. Background technique [0002] Over the past 20 years, biomass fuels, especially biomass granulated fuels, have been widely used in heating furnaces, water heaters, steam boilers and various hot blast stoves and other industries that require heat. There are two typical combustion technologies for biomass fuels in small and medium-sized specifications. The first is gasification combustion. Purification and cooling removes dust, water, wood vinegar, tar, etc. in the gas before burning. The second type is semi-gasification vertical or semi-gasification horizontal combustion. The biomass fuel is burned through the grate or chain row, so that it can be thermally decomposed to produce combustible gas, and then supplemented in the upper part of the grate or chain row. The...
